The Negro Motorist Green Book (at times styled The Negro Motorist Green-Book or titled The Negro Travelers’ Green Book) was an annual guidebook for African-American roadtrippers, commonly referred to simply as the Green Book. It was originated and published by New York City mailman Victor Hugo Green from 1936 to 1966, during the era of Jim Crow laws, when open and often legally prescribed discrimination against non-whites was widespread. Although pervasive racial discrimination and poverty limited black car ownership, the emerging African-American middle class bought automobiles as soon as they could, but faced a variety of dangers and inconveniences along the road, from refusal of food and lodging to arbitrary arrest. In response, Green wrote his guide to services and places relatively friendly to African-Americans, eventually expanding its coverage from the New York area to much of North America, as well as founding a travel agency.
